ok so i made a mistake and i flashed a firmware(the one included in dancemammals firmware editor) onto my htc-039c-rk-v2 (iphone clone) and now the screen is inverted, flashing and unresponsive to touch! It is recognised as a removable disk on my computer (but with no files) but since i cant use the touch screen, i also can't put it in RockUSB mode to update it! (i have the original firmware) How can I put the device in RockUSB mode or get it recongnised as adfu device? I have tried holding down the menu button and even shorting the rockchip IC (all that does is restart the player). Any help would be appreciated!
